“…[Image: see text] Hydroxylamine (HA) can react with hydrogen peroxide (H(2)O(2)) to generate hydroxyl radical (HO(•)), but the reaction rate between them is very slow (2.2 × 10(–4) M(–1) s(–1)). …”

“…The physical analyses of the frontier molecular orbitals agree well with the thermodynamic properties of the selected reagents, and the computed reaction rate parameters. The reactivity of monoterpenes with O(2)(1)Δ(g) follows the order of α-pinene > sabinene > limonene > β-pinene > camphene, i.e., α-pinene and camphene retain the highest and lowest reactivity toward singlet oxygen, with rate expressions of k(T) (M(–1) s(–1)) = 1.13 × 10(8) exp(−48(kJ)/RT(K)) and 6.93 × 10(8) exp(−139(kJ)/RT(K)), respectively. …”

“…Using Au as a model catalyst platform, we observed a zeroth-order dependence of the reaction rate on the H(2)O concentration, strongly suggesting that electron transfer, rather than concerted proton electron transfer, from the electrode to the adsorbed CO(2) is the rate-determining step. …”

“…Comparative performance evaluation of the nanoGO–TiO(2) films on methylene blue photodegradation under UV-VIS and visible light showed that thermal reduction at 200 °C, in synergy with slow photon effects, improved the photocatalytic reaction rate despite the loss of nanoGO and oxygen functional groups, pointing to enhanced charge separation. …”

“…This is attributed to the SFE that provides a smaller average polymer particle size which in turn results in a greater polymerization locus, promoting the reaction rate. The addition of organo-nanoclay during synthesizing polyisoprene significantly lessens the polymerization efficiency because the nanoclay has a potential to suppress nucleation process of the reaction. …”

“…Lastly, the thermal degradation kinetics and photodegradation were used to obtain important degradation factors including the content of anthocyanin residue, degradation index (DI), color parameters, reaction rate (k), and chromatic aberration (ΔE). We found that the extraction condition as using 60% ethanol with 1% citric acid under 80 °C for 40 min was optimal for purple sweet potatoes, which obtained antioxidant capacity as 333 μM TE DPPH, 376 μM TE ABTS(+), and 593.6 μM TE ferric ion reducing antioxidant power (FRAP). …”
